Description
Technical Field
The utility model relates to the technical field of electrolytic cleaning of strip steel, in particular to a polar plate for a strip steel electrolytic cell.
Background
The strip steel electrolytic bath polar plate is an important device for strip steel electrolytic cleaning, and the traditional strip steel electrolytic bath polar plate comprises a polar plate and a polar lug connected with the polar plate through a bolt; the polar plate is cast by stainless steel or carbon steel, and the polar ear is made of copper material; in practical application, because the material electric conductivities of the polar plate and the lug are inconsistent, the polar plate and the copper lug are directly connected and fixed by the bolt, the polar plate and the copper lug have processing errors and installation errors, and a part of gaps are formed between the polar plate and the lug, electric arcs can be generated when strong currents pass through the polar plate and the lug, sparks can be generated in an electrolytic cell, hydrogen can be generated in the electrolytic cell during electrolysis, and thus, if the hydrogen in the electrolytic cell cannot be diluted to the explosion limit in time during the generation of the electric arcs, hydrogen explosion can be generated, and extremely high safety risk exists; meanwhile, the arc and a large amount of alkali fog in the electrolytic bath are corrosive to the polar plate, so that the polar plate is easily damaged.
SUMMERY OF THE UTILITY MODEL
The utility model provides a strip steel electrolytic tank pole plate which can solve the problems that an electric arc of the existing strip steel electrolytic tank pole plate is easy to cause potential safety hazards of explosion and the pole plate is easy to damage.
In order to solve the problems, the technical scheme adopted by the utility model is as follows: the strip steel electrolytic tank pole plate comprises a pole plate and a pole lug connected with the pole plate through a bolt, wherein two outer side surfaces of the connection part of the pole plate and the pole lug are respectively provided with a protective cover covering the bolt; an annular first groove is formed in the wall body on one side of the opening of the protective cover, and annular second grooves corresponding to the respective first grooves are formed in the polar plate and the polar lugs respectively; sealing strips are arranged in the first groove and the second groove.
In the above technical solution, a more specific technical solution may also be: the protective cover is characterized in that connecting parts extending outwards are arranged at the peripheral edges of the opening of the protective cover, and the protective cover is respectively connected with the corresponding pole plate and the corresponding pole lug through locking bolts penetrating through the connecting parts.
Further: the inner side wall surfaces of the first groove and the second groove are arc-shaped surfaces, and the arc radius of the arc-shaped surface of the first groove is 8 mm; the arc radius of the arc-shaped surface of the second groove is 10 mm.
Further: the width of the first groove is 3mm, and the depth of the first groove is 2.5 mm; the width of the second groove is 4mm, and the depth is 3.5 mm.
And further: the length of safety cover is 200mm, and the width is 100mm, and the height is 24 mm.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
due to the structure of the strip steel electrolytic cell polar plate, the polar lug and the environment with hydrogen and alkali fog in the electrolytic cell are isolated during electrolysis, so that the generation of sparks in the electrolytic cell is fundamentally avoided, the explosion of hydrogen in the electrolytic cell is effectively prevented, the production efficiency and the safety of personnel and equipment are greatly improved, in addition, the damage of the polar plate is avoided, the production cost and the safety cost are greatly reduced, and huge economic benefits are created for enterprises.
